Psionics Unbound
A sourcebook for Revised Third Edition fantasy roleplaying, this volume presents psionics as divine power shaped through force of will. It supports campaigns set in Arcanis, where gifted characters defend humanity against the coming Silence and its servants. The book includes eight base classes, more than one hundred feats, over thirty prestige classes, hundreds of psionic powers, psionic items and equipment, creatures, and spells that let magic-users temporarily channel mental power. The rules are refined for use as a complete psionics system in any compatible campaign.
